Hi @Budour AlHarbi ,

You can have a look at this thread, which may be a similar issue.

Steps to connect LocalDB to Visual Studio Server Explorer:
Open command prompt
Run SqlLocalDB.exe start v11.0
Run SqlLocalDB.exe info v11.0
Copy the Instance pipe name that starts with np:...
In Visual Studio select TOOLS > Connect to Database...
For Server Name enter (localdb)\v11.0. If it didn't work, use the Instance pipe name that you copied earlier. You can also use this to connect with SQL Management Studio.
Select the database on next dropdown list
Click OK

Answer 2

Could you give us some information why you expect this to work?

It seems from the error message that you don't have localdb installed. Is this something you can verify or refute?

If you have localdb installed, have you created an instance called v11.0? If you run

sqllocaldb info

what do you see?
